The utility model relates to ceramic fiber cotton processing equipment technical field, and disclose a kind of ceramic fiber cotton processing silk throwing device, including placing mechanism, is equipped with silk throwing placement bin, auxiliary turning-out groove is opened in the top of silk throwing placement bin, and assembly hole and support are equipped in bottom, rotating mechanism is constituted by speed reducer and connecting frame, and the output of speed reducer is connected with the connecting frame. The utility model is convenient to drive silk throwing assembly and rotary drive mechanism to turn out silk throwing placement bin by rotating mechanism and arc auxiliary turning-out groove cooperation, solve traditional device material loading and unloading difficult, component maintenance inconvenient problem, greatly improve operation efficiency and device maintainability, reduce manual operation intensity.

The invention relates to the technical field of refractory thermal insulation materials, in particular to a high-temperature-resistant marine rock wool product and a preparation method thereof. The high-temperature-resistant marine rock wool product specifically comprises the following components in parts by weight: 85-95 parts of a rock wool material, 1-10 parts of an adhesive, 2-4 parts of a silane coupling agent and 3-5 parts of a water repellent. According to the invention, through a high Al2O3 rock wool skeleton, Na2O and K2O are introduced as fluxing components, and the fire resistance, heat preservation, hydrophobicity and mechanical properties of the marine rock wool are synergistically improved by using the multi-element modified phenolic resin, so that the marine rock wool has a good application prospect.

The utility model discloses a device for reducing the content of ceramic fiber slag balls based on multi-stage separation, which comprises a three-stage airflow separation chamber which is internally divided into a first-stage airflow separation chamber, a second-stage airflow separation chamber, a third-stage airflow separation chamber and a fiber settling and collecting chamber, the first filter screen, the second filter screen and the third filter screen are arranged in the bottoms of the first-stage airflow separation chamber, the second-stage airflow separation chamber and the third-stage airflow separation chamber; the first, second and third centrifugal fans are arranged in the first, second and third-stage airflow separation chambers; the slag ball collecting box is arranged at the bottom of the third-stage airflow separation chamber; the bag-type dust collector is arranged at the top of the fiber settling and collecting chamber; the fiber conveying belt is used for conveying the pure ceramic fibers collected in the fiber settling and collecting chamber into the fiber collecting bin. According to the utility model, the combined use of multi-stage airflow separation and multi-stage screening is utilized, so that the content of slag balls in the ceramic fibers is obviously reduced, and the flexibility and the heat-insulating property of the ceramic fibers are obviously improved.
